By default a just \ref compute_anchor "computed" mesh will be
|
|
automatically displayed in the <b>VTK 3D Viewer</b>. (You can switch
|
|
off \ref automatic_update_pref "Automatic Update" preference parameter
|
|
to prevent this.)
|
|
Click <b>Display only</b> to hide all other objects at the same time.
|
|
|
|
<b>VTK 3D Viewer</b> is described in detail in the documentation on <b>GUI module</b>.
|
|
|
|
Use the following \ref mesh_preferences_page "preference parameters"
|
|
to adjust how the mesh is displayed by default:
|
|
- \ref automatic_update_pref "Automatic Update"
|
|
- \ref display_mode_pref "Default display mode"
|
|
- \ref quadratic_2d_mode_pref "Representation of the 2D quadratic elements"
|
|
- All parameters of \ref mesh_tab_preferences "Mesh" tab page of the
|
|
Preferences dialog.
|
|
|
|
After the mesh has appeared in the Viewer, you can select it with
|
|
left mouse click and get information about it, change its
|
|
presentation parameters and access to other useful options by
|
|
right-clicking on the selected mesh.
